摘　　要：施工中遇到的中风化岩石使得人工凿孔施工进度缓慢,施工成本增加。采用小孔埋置炸药爆破方法,通过对工程环境、岩石爆破技术中的炸药量、预埋炸药炮孔位置、一次起爆最大药量等因素的控制,使得爆破工作安全顺利完成,很好地解决了施工难题,加快了进度并降低了成本,桩长也达到设计要求。Pile encountered in weathered rock artificial dig hole and artificial borehole construction progress slowly increase the construction cost.Using the small hole buried explosive blasting method,based on the engineering environment,rock blasting technique in explosive metering,pre-buried explosive hole location,a maximum initiating dosage control,the blasting safety was completed,a good solution to the difficulty of construction to speed up the progress and reduce the cost of the pile length to meet the design requirements.

关 键 词：人工挖孔桩 爆破 装药量 安全
